As the others mention, if these are properly defined in a dictionary or map, use: 
 a!localVariables(
 local!data: {
 a!map(list: {1,2,3}),
 a!map(list: {56,76,54,32}),
 a!map(list: {12,23,45,54,32,54}),
 a!map(list: {1,2,3,4,5,6,7}),
 a!map(list: {8,9,10,11,12,13,14,15})
 },

 a!richTextDisplayField(
 value: a!richTextBulletedList(
 items: a!forEach(
 items: local!data,
 expression: a!richTextListItem(
 text: concat(
 "length of array ",
 fv!index,
 " is ",
 count(fv!item.list)
 )
 )
 )
 )
 )
)

a!forEach(
 items: {
 a!map(
 id:{1,2,3},
 ),
 a!map(
 id:{1,2,3,7,9},
 )
 },
 expression: "Length of the array " & fv!index & " is " & length(fv!item.id)
)

a!localVariables( local!data: { a!map(list: {1,2,3,8,9,9,9,9,9,80,90,70}), a!map(list: {56,76,54,32}), a!map(list: {12,23,45,54,32,54}), a!map(list: {1,2,3,4,5,6,7}), a!map(list: {8,9,10,11,12,13,14,15}) }, 
 a!richTextDisplayField( value: a!richTextBulletedList( items: a!forEach( items: local!data, expression: a!richTextListItem( text: concat( "length of array ", fv!index, " is ", count(fv!item.list) ) ) ) ) ) )

Use a list of dictionary instead, where each dictionary has an array as one of its properties.
