Alex says that the secretary will type up the minutes for today's meeting.

In this context, "minutes" are a written detailed description of what was discussed during a meeting.

It's used as a record of the meeting to tell you what happened in the meeting, we call those the "minutes," it's always plural.

Normally someone is assigned, or asked, to take minutes - note the use of the verb "to take" with this noun, "minutes" - to take minutes for a business meeting, because then, later on, people can remember what happened at the meeting by looking at the minutes.

The minutes are not usually a transcript; that is, they don't have every word that everyone said.

It's like a summary of the main things - the main ideas - of the meeting.

Alex says that the secretary will distribute the minutes via email for comments.

The word "via" (via - sometimes pronounced "via") means through, by, or by way of, so in the expression "distribute the minutes via email" we mean to send the minutes - the document that has the summary of the meeting - to people by email, probably as an email attachment.

Alex says that the secretary will distribute the minutes via email for comments.

A "comment" is, in this case, an opinion about something, or a statement about whether one likes or agrees with something.

The minutes will be distributed for comments so that people can say whether they agree with the minutes or if they think something needs to be changed or added.
