You’ll need to be able to write and debug code.

You can create a template overload of this file:
buddypress\bp-templates\bp-legacy\buddypress\members\single\profile\profile-loop.php

Set a variable with the current user role. Google how to get that value.

Then create an array of profile field ids for a role.
For example :

if ( $current_role == 'model' )
    $show_fields = array( 1, 5, 23 ); 
elseif( $current_role == 'photographer' ) 
    $show_fields = array( 1, 7, 12, 35 );

Then check if the current profile field is in that array.
Something like:

<?php while ( bp_profile_fields() ) : bp_the_profile_field(); ?>

	<?php if ( in_array( bp_get_the_profile_field_id(), $show_fields ) ) : ?>
	
		<?php if ( bp_field_has_data() ) : ?>
	
			<tr<?php bp_field_css_class(); ?>>
	
				<td class="label"><?php bp_the_profile_field_name(); ?></td>
	
				<td class="data"><?php bp_the_profile_field_value(); ?></td>
	
			</tr>
	
		<?php endif; ?>
		
	<?php endif; ?>

Avoid setting any fields to ‘required’ if you’re only going to show them based on role.
