..hey guys...could you pls identify any of these diodes. ???..got a handful of them on my closet...maybe you have encountered them in your pedal building...one of them could be the TS808 ma150...tnx in advance..

I'm no expert, but the bottom pic looks like 1n34a's

Post their Fv.
Chances are slim to none that they will be identifyable, but I can at least tell you what they'll be close to.
...tnx guys..the ff: are the vf
(1) 0.477 - 0.479
(2) 0.486 - 0.497
(3) 0.484 - 0.487
(4) 0.497 - 0.503
(5) 0.229 -0.248
The last one's most likely russian, D9B or D9V or similar. Those are usually marked with red bands and the Fv is in that range.
Since they're mostly silicon, I wouldn't fuss over it too much. MA150 are just 1n4148, which are just 1N914. They're all "equivalent" diodes and in my experience are indistinguishable. I think I've seen 1N914 like #2.
#4 COULD be Zener. I'm not entirely certain how to measure that except to set it up in a way that would shunt off voltage.
...thanks a lot Jon...you really are ever reliable...i'll just play with them and see if they are like the in4148s...thanks again!....
bottom ones are definately 1n34A, I have a handful of those myself.
..tnx aballen...
to be more specific these are the ones I have they are identical.

Steve calls the "work-alike"... so not actually 1n34a, but good enough in my book
..its good to know... ;)

Steve's work alikes can be any number of different part types; I have a bag full of them and none are red.
I've also noticed that all clip closer to .26v, which is a full .1v lower than any 1n34A I've ever encountered. So what I'm saying is, it's by no means a foregone conclusion that they're 1N34A and unlikely given the Fv (unless the op has a known 1n34A to compare Fv with -- his multimeter seems to read lower than mine).

..found this..http://www.eonet.ne.jp/~k-matsu/germanium_diodes.html (http://www.eonet.ne.jp/~k-matsu/germanium_diodes.html)
i guess this is somewhat similar to #5
