Movie Title Unknown

Trying to figure titles to 4 different movies that I watched on TV about 40 years ago and have not seen since. I remember certain scenes as follows:

1. Protagonist being chased by bag guys ( possibly Nazis in Africa.) They follow him to some type of structure. He is unarmed except he has a single round from a rifle. He places it in a hole in the door and strikes it with a rock causing it fire, shooting one of his pursuers.

2. Several people are under attack by what appear to be natives or native Americans. They are inside one or more structures fending them off. The odd thing is that their weapons are machine guns rather than the usual rifle or "six shooter". Possibly a " B" picture and also possible location in south America.

3. Airplane goes down on some island or remote area and survivors come under attack by natives. Some are killed. Likely another "B"  pictures and likely made in either 60s or 70s. Possibly staring Peter Graves but definitely not sure.

4. WW 2 Movie, allied troops are behind enemy lines at what appears to be an airport air strip with numerous fighter plains. The 2 sides start to fight each other and allied soldiers manage to get inside 1 or more plains and fire on the Germans from the gun turrets inside the planes, while the plains are on the ground. Also the allied troops have a type of " metal clicker device" to single each other. The scene is taking place, I believe while it's dark.
