1. after opening 1Cl/1D with 5 card suit - 11-14 HCP and getting the 1H/1Sp response - what do you bid:
1NT or 2Cl/D..., and does it depend on if responder was a passed or nonpassed hand?
2. after responding to 1Cl/D with 5 card suit 6-10HCP 1H/Sp and getting 1NT re-response - what do you bid:
Pass or 2 of your suit..., and does it depend on if you were a passed or nonpassed hand?

My opinion -
1) Doesn't depend on passed/non-passed. Depends on the quality of you suit. With 4 of the top 5 or the AKQ I would rebid my suit. With less I would bid 1 NT.
2) As a non-passed hand I would rebid my suit if it was strong (see above), and pass if it wasn't.  As a passed hand I would pass, except with a strong suit AND I was at the top of the weak range (10 or a good 9).

1. after opening 1C/1D with 5 card suit - 11-14 HCP and getting the 1H/1Sp response - what do you bid:
1NT or 2C/D..., and does it depend on if responder was a passed or nonpassed hand?

You left a few things out, so I assume you meant something like 5-3-3-2 distribution. Where 2 is not in partners suit. For if I had three card support, the option to raise to 2H/2S would also be available. I would raise with three cards and a minimum type hand. So for instance, 1D-(p)-1H-(p)-2D is pretty much always a six card suit. With 4S or 4C I would bid that suit. With three card support I would tend to raise (unless with extra values).

In my case, the 1NT rebid, especially if partner is a passed hand, would be more typical. I don't need stoppers in both of my 3 card suits.

"2. after responding to 1Cl/D with 5 card suit 6-10HCP 1H/Sp and getting 1NT re-response - what do you bid: Pass or 2 of your suit..., and does it depend on if you were a passed or nonpassed hand?"

With a five cards suit I would pass. Why, see above, since I expect my partner to raise with three cards support on many hands (yes, I know this is not a popular treatment - most people require four cards for this raise). If you raise with three card support when weakish, then over NMF, you can then rebid 2 of your partner suit with a doubleton honor (otherwise you need three card support) or jump to 3 of the major with three card support, as you will also have the promised extra value. Also, if the bidding goes 1D-(p)-1H-(p)-1NT-(p)-2D-2H is safe type of bid, as it shows three card support plus extra values (to "good" for 2H originally given the 1NT rebid).

Great Question!
You actually touch one of the most important points in SAYC.

There are 6 key points:
1) pass instead open bid.
If with such a hand
S ××
H ××
D KJ××
C AK×××

2) rebid 1NT
S ××
H ××
D KQ×
C AKJ×××

1C 1H
1NT

3) support P's suit
S ×
H ×××
D KQ××
C AKJ××
1C 1H
2H

4) rebid 2c only you have 6 card suit
S *
H Q**
D K××
C AQJ×××
1C  1S
2C

5) (some experts) will rebid 2C with such a hand instead above hand.
S K××
H A××
D ×
C AK××××
because they do not want to miss 3NT when P has
such a hand.

S A**
H ****
D J10**
C Q*

6) change your system(or part of your system) .
Many experts prefer this way.
