i love my Konica Auto S1.6 but i sometimes feel the 45mm lens is too limited.
so i am tempted to try an aux. lens set which i have little knowledge.
what puzzle me most is the f-stop on the aux lens, some said f5.6, does it
mean the aperture has to be set fixed at f5.6?
and can i fit a Yashica (or other makers) made aux set on my Konica?
any advice is welcome.

I think f-stop of aux lens limits usable aperture range to max aperture of adapter, f/4 or f/5.6 (I think, Yashica aux lenses were f/4).
Hate to say this but people happily threw away their aux lenses when SLR's offered various focal lengths with ease of TTL, I'm not even mentioning universal zooms like 28-100 or 24-105.

Hate to say this, but many people have decided that primes have a very useful life with SLRs. I still have some zooms, but they are not always what I reach for first in SLRdom. But to each his own, and I do sometimes reach for zooms myself, just not as much as I used to.
I think what you are looking at is that the whatever the wide open on your Konica was, it will change to what is on the aux lens. I never used one, but they were always reported not to be that good.
Of course, why should they be? More glass will almost always cost some resolution and/or contrast. Will it be little enough you still like to use it? I think they are usually inexpensive enough it is worth it for you to try and see.

I'm glad to say that I use FFL lenses on SLRs (like wide and superwide, and even about normal).
I clearly remember bidding on my first RF - Yashica 35 Electro, with aux lenses in separate auction. Googling a bit how they are used I got impression they are curiosity items. Until then I used only cameras with fixed lens so I decided I should get my first SLR to be able to change focal length on same camera as aux lenses put too much restrictions to be practical. I even didn't put initial bid on aux lenses and they were won by someone who probably needed finder.
Regarding zooms, I still think there are some really usuful ones - like 25-50/4 or 28-100/4 but I can agree they aren't for everyone.

I haven't given up completely on zooms myself. Just starting to prefer my FFL lenses.
I have a set of three zooms that go from 18mm to 150mm for C/Y mount. Very useful range for me as I see wide more than long. The zooms aren't the highest quality brand names (in fact, one is a Phoenix), but they are rather good photo takers. A 25-50 would work for me I think, and I have a 28-70 I like, but a 28-100 sounds a little long and/or heavy for me.
In screw mount I have 18mm, 28mm, 35mm, 50mm, 135mm, 200mm, and 300mm. That always seemed to give me what I needed before I jumped on the zoom bandwagon. Especially the 18mm, 28mm, 50mm, and 135mm. But there are times I like to use the zooms as well. The Contax 167MT is a fun camera.
But to each his own. I like what I have and if you do as well, there are at least two happy photographers out here.

The biggest problem with auxiliary lenses is they are not matched to the lens you are mounting them on. Plus, adding another air gap for the light to pass through creates it's own set of problems. Then take into account that you would be constantly adjusting the focus, thus eliminating any chance of taking a quick shot when it presents itself. I will sometimes buy a set of axiliaries to complete a collectable set, but not very often. The finders though tend to be a good substitute for the more expensive OEM ones that are missing from other rangefinder lenses, and will sometimes be the only reason one buys an aux set. Then, you only have a marginal difference in focal length with most of them, so it's not a compelling reason to buy one.
