Can people pray kaza(delay) prayer in Jamaat(together by someone is Imam)? It means Maghrib time is very short and the time is over and also the time of Fajr(means after sun rise), can people pray that prayer in Jamaat(means together by making someone as Imam).

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

It is permissible for the people who missed the prayer until its time expired to make it up in congregation. It is confirmed in a long Hadeeth that the Prophet and his Companions overslept and did not pray Fajr on time when they came back from one of the battles and they did not wake up until they saw the  sun up in the sky. Then the Prophet performed ablution and ordered Bilaal to make the Iqaamah (the announcement that the prayer is about to begin) and then the Prophet led them in the prayer [Fajr prayer].” [Muslim]

However, a Muslim should endeavour to establish the prayer at its prescribed fixed time, especially the prayers that are preceded by sleep, like the Fajr and ‘Asr prayers.

Allaah Knows best.
