×We did many activity yesterday.

"Activity" is a countable noun when referring to specific events or actions. Use the plural form "activities" when talking about multiple events.
×Main activity of the day is hiking.
✓The main activity of the day is hiking.
When "activity" is specified or defined (e.g., with "main", "primary", "first"), it usually requires a definite article ("the") or an indefinite article ("an") if it's singular and unspecified.
×His sudden activity surprised everyone.
✓His sudden action surprised everyone.
"Activity" usually refers to an ongoing process or a planned event, while "action" refers to a single deed or something done. Use "action" for a specific, often sudden, act.
×These activity is very interesting.
✓These activities are very interesting.
The demonstrative adjective "these" must agree with a plural noun. Use the plural form "activities" and the plural verb "are".
×She has no activity on the project.
✓She has no activity on the project. (Acceptable) / She is not involved in any activity on the project. (More natural)
While "activity on" can be used, the more common and natural preposition for involvement is "in an activity". The original sentence, while not strictly wrong, sounds awkward. A more natural phrasing uses "involved in" or "participating in".
×The room was full of activities.
✓The room was full of activity.
When "activity" refers to the general state of being active, movement, or busyness (not specific events), it is used as an uncountable noun. Use the singular form without an article in such contexts.
