more saban shows

I know that there were other saban shows that actually had a lot of cross over moments with each other. what were they? i know there was this and power rangers, but there was also one where like the 3 heroes wore these suits that were 2 color scheme (one was red and blue i know) with like metal things on them, and i know that there was a show where there was like an alien came to earth and lived with a family and he was some kind of green ranger and in a later cross over it was revealed that his home planet is where alpha 5 was built. i know this is kind of confusing but does anybody know?
