Model Foo

from odoo import models, fields, api
class Foo(models.Model):
    _name = 'foobar.foo'
    name = fields.Char()
    age = fields.Integer()
    length = fields.Float(digits=(5, 2))
    question = fields.Selection(selection=[('yes', 'Yes'), ('no', 'No')], string='Question')
    gender = fields.Selection(selection=[('male', 'Male'), ('female', 'Female'), ('other', 'Other')], string='Gender')

Model Bar

from odoo import models, fields, api
class Bar(models.Model):
    _name = 'foobar.bar'
    name = fields.Char()
    foo_1_id = fields.Many2one('foobar.foo')
    foo_2_id = fields.Many2one('foobar.foo')
    foo_3_id = fields.Many2one('foobar.foo')

View Form Foo

<record id="view_foobar_foo_view_form" model="ir.ui.view">
        <field name="name">Foo Form</field>
        <field name="model">foobar.foo</field>
        <field name="arch" type="xml">
            <form string="Foo Form">
                <sheet>
                    <field name="id" invisible="1"/>
                    <group name="group_data" col="1">
                        <group col="6">
                            <field name="name"/>
                            <field name="age"/>
                            <field name="length"/>
                            <field name="question"/>
                            <field name="gender"/>
                        </group>
                    </group>
                </sheet>
            </form>
        </field>
    </record>

View Form Bar

    <record id="view_foobar_bar_view_form" model="ir.ui.view">
        <field name="name">Bar Form</field>
        <field name="model">foobar.bar</field>
        <field name="arch" type="xml">
            <form string="Bar Form">
                <sheet>
                    <field name="id" invisible="1"/>
                    <group name="group_data" col="1">
                        <group col="2">
                            <field name="name"/>
                        </group>
                        <group col="6">
                            <field name="foo_1_id"/>
                            <field name="foo_2_id"/>
                            <field name="foo_3_id"/>
                        </group>
                    </group>
                </sheet>
            </form>
        </field>
