Trying to determine type of caps these three are so as to find replacements.
Any help would be greatly appreciated.

In the case that the identical type (ie, tantalum, etc.) is not available
locally, what type can I use to replace these? I have this selection to
choose from at my local electronics shop:
- monolythic ceramic
- ceramic Disc
- dipped tantalum
and a limited selection of:
- dipped silver mica (metallized polyester film)
- mylar (metallized polyester)

If these are inappropriate as replacements, I'll order the appropriate ones,
but would like to get this fixed today.

These caps are used on a car alarm PCB (not in the RF stage).

(All of these caps are "tubular" in shape; no vertical height, per se.)

What's "K5R" ?

I have the color codes and can figure out the values, but what type of cap is
this? A fourth type is similar to this type, but has a pink background.

Thanks,
I'm afraid your going to have to get out a general component supplier
catalogue and look at the pretty pictures!

The 104K refers to the value (100000pf) and the temp co-efficient.
The K5R is the dielectric used in the manufacture of the cap
+35M is the working voltage - not sure of the M.

But you really need to find the manufacturer (by looking for similar
pictures) and then search their site for caps that match the ones
youve got.

By the way I can't access your pictures (even when I fix for the
word-wrap).

Sorry that should read:
The 104K refers to the value (100000pf) and the tolerance (10%).
The K5R is the dielectric used in the manufacture of the cap
+35M is the working voltage M = 20% tolerance.
