There is not a set height that the American Flag needs to be flown at, but it does need to be flown at the top of the flagpole. If other flags, such as State or POW/MIA, are flown around the American flag then the American flag needs to be flown above the other flags.
NO. as approved by congress "NO STATE FLAG" shall be flown above the American Flag.
The American flag should be flown above a light as a sign of respect
This will all depend on which flag is flying alongside or below the American flag. If being flown with flags of other nations, they should all be raised to the same height and are never to be flown on the same pole. If being flown with a state, city or organizational flag, the US flag will fly above the other flag in a larger size. On most standard sized flagpoles, the American flag will be a 3'x5' flag and the other flag will be a 2'x3' flag. If the US flag is flying along a different flag on separate flagpoles, the flags can be of equal height but the US flag will then need to fly on the extreme left of the other flags. This left side is known to be a prominent flag. When flown with flagpoles displaying non-national flags, the American flag will be raised first and lowered last. There is a link below.
None on US soil.
When it is displayed from the same flagpole with another flag - of a state, community, society or Scout unit - the flag of the United States must always be at the top except that the church pennant may be flown above the flag during church services for Navy personnel when conducted by a Naval chaplain on a ship at sea. http://www.usflag.org/flagetiquette.html
Any flag flown upside down is a signal of distress.
The American Flag always has precedence by flying higher than other flags .
No as the U.S house of congress is a American state building only the The U.S flag can fly there.
Any state flag should be flown below or level with the US Flag, but never above it. If it is on the same level it should be on the right, this includes Texas. The rumor that Texas is the only state that is allowed to fly at level with the US Flag is just that a rumor and an urban myth.
It is not illegal, but it is against tradition and protocol and would not be proper. The United States flag flies on top, then beneath that the state flag, and then beneath that, the Confederate flag may be flown.
The American Flag should always be flown higher than the state flag and should be flown a half-mast when in peril or in rememberance.
