Thank you for your help so far. It is showing the featured event but not the rest. 
There appears to be a problem with the query args (starting at line 57 of Ravi’s version). They are such that the query will not return anything. You should be seeing “Sorry, no posts matched your criteria.” If not, something else is wrong. Do you have WP_DEBUG defined as true in wp-config.php? You should, so you can see any PHP errors immediately.
In the query args, ‘meta_type’ is not a valid argument. There is a ‘type’ argument that is only used as part of a ‘meta_query’ array. In that context, ‘meta_value_datetime’ is an improper value. Simply ‘DATETIME’ would be correct.
Outside of ‘meta_query’, you need either a ‘meta_value’ or ‘meta_value_num’ argument along with a ‘meta_compare’ argument (unless the default ‘=’ is desired) to go with ‘meta_key’ in order to have complete, valid meta data criteria as part of the query. Since your data is neither CHAR nor NUMERIC, IMO you would be better off using ‘meta_query’ instead of ‘meta_key’ etc. See https://developer.ww.wp.xz.cn/reference/classes/wp_query/#custom-field-post-meta-parameters
The issue was not with the query args and I am still having issues thank you moderator. @ravipatel think you can help?
