The plant on left in your first photo and the leaf in your second photo looks to be a cane type Begonia:

My eyes aren't the best but the other plant doesn't look like
Lipstick Plant (Aeschynanthus) but rather a Hoya, possibly
Wax Plant (Hoya carnosa) or
Wax Plant (Hoya pubicalyx)
If the second plant is actually a Hoya, in my opinion they should not be planted together as the two require entirely different growing conditions. While the Begonia likes consistently moist soil, the Hoya is more succulent and stores water in those thick leaves, requiring much less water.
Hopefully others will pop in with suggestions before long.
