I am doing a research on motivation. The respondents are from one of Yemeni colleges. Are 50 respondents enough?
it mainly depends on your research population, sampling technique, statistical test utilizing, and intended research outcome.

The sample size depends on the target population and the statistical methods used to analyze the obtained data.
By convention a minimum sample size of 30 is needed to do a statistical research .I think 50 is enough for an exploratory or pilot study .For a case study a minimum of one case is required
As you wrote that you intend to research on "motivation", which is very popular topic to study, so you should have good research sample. There are different approaches for deciding number of responses or sample size. As a rule of thumb, one should use multiplier of minimum five to determine the sample size i.e. if you are having 30 questions in your questionnaire multiply it with 5 = 150 responses (minimum). To have a good sample size, researchers prefer to have multiplier of 10 e.g. for questionnaire having 30 questions/items multiplier of 10 will determine 300 good sample size.
